Stretch four

In basketball, a stretch four (sometimes called a stretch big) is a player at the power forward position that can shoot further from the basket than a conventional power forward. "Stretch" describes the effect that such a player has on the opposition's defense, and the power forward position is also known as the "four"; hence "stretch four". The stretch four is a fairly recent innovation in the NBA (with an "explosion" of players coming through since the 1999–2000 season), but is still becoming increasingly common in today's game, as many NBA coaches now use the "small-ball" line-up/tactical play.
